Member Typedef Documentation

typedef COMPLEX imgbase< s_x, s_y, COMPLEX >::data_t [inherited]

The base data type, for convenience.

You can use this typedef to extract the type of the elements from the derived classes.

Example:

          bild16::data_t temp;

COMPLEX & imgbase< s_x, s_y, COMPLEX >::operator()	(	int	y,
		int	x
	)			[inline, inherited]

Element extraction operator.

Parenthesis are used to index a pixel of the image. This idea is borrowed from the octave C++ interface. The order of the arguments is y, x. This order should imitate the old C way in order not to confuse people from EP~V

Definition at line 138 of file imgclass.hpp.

const COMPLEX & imgbase< s_x, s_y, COMPLEX >::operator()	(	int	y,
		int	x
	)			const [inline, inherited]

Constant element extraction operator.

Definition at line 140 of file imgclass.hpp.

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator/=

(

const imgbase< s_x, s_y, COMPLEX > &

what

)

[inherited]

Arithmetic operator.

This operator divides every pixel of the image by the corresponding value in what. It leaves the value unchanged if the denominator is zero, thus avoiding division by zero

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator/=

(

const COMPLEX &

what

)

[inherited]

Arithmetic operator.

This operator divides every pixel by the constant value what

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator*=

(

const imgbase< s_x, s_y, COMPLEX > &

what

)

[inherited]

Arithmetic operator.

This operator multiplies every pixel of the image by the corresponding value in what.

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator*=

(

const COMPLEX &

what

)

[inherited]

Arithmetic operator.

This operator multiplies every pixel by the constant value what

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator-=

(

const imgbase< s_x, s_y, COMPLEX > &

what

)

[inherited]

Arithmetic operator.

This operator subtracts every pixel of what from the corresponding value in the image.

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator-=

(

const COMPLEX &

what

)

[inherited]

Arithmetic operator.

This operator subtracts the constant value what from every pixel in the image

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator+=

(

const imgbase< s_x, s_y, COMPLEX > &

what

)

[inherited]

Arithmetic operator.

This operator adds every pixel in what to the corresponding pixel value in the image

imgbase<s_x, s_y, COMPLEX >& imgbase< s_x, s_y, COMPLEX >::operator+=

(

const COMPLEX &

what

)

[inherited]

Arithmetic operator.

This operator adds the constant value what to every pixel in the image
